Physics of Electron-Photon Interaction
Abstract
A continuation of the experiment examining the sticking probability of energetic alkali ions on Ge is described. Results are given for the Ge(100)-Cs system in the zero coverage region. Experimental difficulties which forced discontinuation of the study are discussed. A study of the Ge(100)-Cs-O photosurface is described with particular emphasis on the structural changes associated with cathode formation. A stable negative electron affinity Si(100)-Cs-O photocathode was obtained and the optimum amount of Cs determined to be 1.3 monolayer. A work function value of approximately 0.6 eV was measured. Experimental results of an electron scattering experiment on Ge(100) are summarized. A full report is forthcoming. Auger spectra obtained from vacuum-cleaved alkali halide crystals are presented and some of the difficulties encountered are summarized. Preliminary evaluation of the use of Auger spectroscopy for the analysis of aqueous solutions is described. A description of a system for studying complex photocathodes is given.
